Private Well Testing FAQ

State Hygienic Lab - The University of Iowa Private wells are not subject to federal regulations that apply to public drinking water systems. Therefore, it is up to well owners to regularly monitor the safety of their drinking water to ensure it is safe for human consumption. Public drinking water systems are required by federal regulations to be tested for various contaminants at specific intervals.

Iowa Source Water Protection Program

Source Water is a lake, stream, river or aquifer where drinking water is obtained. Source Water Protection (SWP) is the act of preventing contaminants from entering public drinking water sources. SWP includes both ground water (wellhead) protection and surface water protection. The IDNR SWP Program is a voluntary program and is divided into Targeted and Non-Targeted programs in order to provide better customer service to our Iowa Community Water Supplies (CWS).
